System and method for price matching through receipt capture

ABSTRACT

A system and method for generating a notification of a price change for a transaction and facilitating an associated price adjustment based on electronic image capture of a paper receipt. An image capture system captures an electronic image of a paper transaction receipt, which is transmitted to a data extraction processor that extracts transaction receipt data from the captured electronic image. A unique key is generated by an authentication server that is matched to a transaction record to generate a reliability score for the OCRed image and to authorize price matching. If the price monitoring server identifies that the price of a purchased transaction item has changed, the price monitoring server automatically generates a notification to the user indicating the price change and an email to the customer service department of the merchant from which the transaction item was purchased, requesting a price adjustment that is credited back to the payment instrument.

FIELD OF THE DISCLOSURE

The present disclosure relates to systems and methods for generating a notification of a price change for a transaction and facilitating an associated price adjustment based on electronic image capture of a paper receipt for the transaction, utilizing a unique key that is generated to verify the transaction.

BACKGROUND OF THE DISCLOSURE

Currently, it is extremely difficult for customers to seamlessly learn when the price for something which they have purchased has been reduced, either by the merchant where the item was originally purchased or at a different merchant, such that a savings resultant from a price guarantee can be obtained. Furthermore, in response to learning that the price on something they have bought has been reduced, customers typically must undergo the inconvenience of manually having to contact or visit the selling merchant to request the refund, including bringing proof of where the lower price was offered to justify to the merchant that the price should be reduced. Where some limitation of the price guarantee, or defect in the available proof, precludes the merchant from applying the price guarantee, the purchaser will likely believe that they have wasted their time, reducing the likelihood that they will seek refunds under price guarantees in the future, costing the consumer their hard earned resources. For some purchases for which a user has an email receipt, a price tracker application may be utilized to tell customers when the price on something they purchased has changed. However, customers are not provided with such notifications for those purchases where an email receipt is not available.

When a customer requests a price match, there is also a need for verification that a customer requesting to receive a credit for the associated price adjustment actually purchased the item for which the customer is requesting the price adjustment. Additionally, after a customer has received a price adjustment, if the merchant does not keep track of the specific price adjustment, the customer may attempt to return the price adjusted item and receive a credit for the original price, not the price adjusted price.

These and other drawbacks exist.

SUMMARY OF THE DISCLOSURE

Various embodiments of the present disclosure provide systems and methods for generating a notification of a price change for a transaction and facilitating an associated price adjustment based on electronic image capture of a paper receipt for the transaction. A price matching system may include a client device, a merchant system, a data extraction processor and an account provider system.

An image capture system on a client device may be utilized to capture an electronic image of a paper transaction receipt, which may be transmitted to a data extraction processor, which may include an optical character recognition (OCR) device. The data extraction processor may extract transaction receipt data from the captured electronic image.

Upon extracting enhanced transaction information from the transaction receipt, a unique key may be generated by an authentication server. For example, the enhanced transaction information may include the timestamp of the transaction. This unique key may be matched to a stored transaction record, and as such, may be utilized to generate a reliability score for the OCRed image. If the unique key is matched to the transaction record, the system may authorize price matching.

A price monitoring server may utilize a web crawler as an item level price tracker to facilitate price matching by searching for a price change of an item identified on a user's transaction receipt through the electronic data extraction. The price change may include a reduction in price, and/or an application of a coupon, credit, or rebate. If the price monitoring server identifies that the price of a previously purchased transaction item has changed, a price adjustment server may automatically generate and transmit a notification to the user indicating the price change. The price adjustment server may also automatically generate and transmit an email to the customer service department of the merchant from which the transaction item was purchased, requesting a price adjustment that is credited back to the payment instrument used in making the transaction.

In an example embodiment, a client device may include a mobile device that may utilize location-tracking systems and methods, such as geo-fencing technologies, to determine the current location of the customer mobile device. A price monitoring server 156 may be utilized to determine whether the location of the customer mobile device matches a merchant location for which price matching has been identified. If a match is identified, the current location of the customer mobile device may be transmitted to the price adjustment server, which may, in real time, transmit a notification to the customer mobile device indicating that the customer has a price matched credit at the current merchant location.

A UICC may identify a user to a wireless operator, store contacts, enable secure connections, and add new applications and services, such as a transaction system.

Input/output device 122 may enable Industry Standard NFC Payment Transmission. For example, the input/output device 122 may enable two loop antennas to form an air-core transformer when placed near one another by using magnetic induction. Input/output device 122 may operate at 13.56 MHz or any other acceptable frequency. Also, input/output device 122 may provide for a passive communication mode, where the initiator device provides a carrier field, permitting answers by the target device via modulation of existing fields. Additionally, input/output device 122 also may provide for an active communication mode by allowing alternate field generation by the initiator and target devices.

Input/output device 122 may deactivate the RF field while awaiting data. The attachment may use Miller-type coding with varying modulations, including 100% modulation. The attachment may also use Manchester coding with varying modulations, including a modulation ratio of 10%. Additionally, the attachment may be capable of receiving and transmitting data at the same time, as well as checking for potential collisions when the transmitted signal and received signal frequencies differ.

Client device 120 may also include various software components to facilitate the account, payment, and transaction operations including an App Processor. For example, client device 120 may include an operating system such as, for example, the iOS™ operating system from Apple, the Google Android™ operating system, and the Windows Mobile™ operating system from Microsoft. Client device 120 may also include, without limitation, software applications such as mobile banking applications and financial institution applications to facilitate ordering and payment, an NFC application programming interface, and software to enable touch sensitive displays. Mobile device manufacturers may provide software stacks or Application Programming Interfaces (APIs) which allow software applications to be written on top of the software stacks. For example, mobile device manufacturers may provide, without limitation, a card emulation API to enable NFC card emulation mode, a logic link control protocol (LLCP) API for peer-to-peer communication between mobile devices, a Bluetooth™ API supporting BLE, and a real-time data (RTD) API and a NFC Data Exchange Format (NDEF) API for reading/writing.

The App Processor may enable execution of software applications on client device 120. In various embodiments, the App Processor may cooperate with the NFC technology to enable a payment using client device 120. Additionally, client device 120 may include an attachment for contactless payments (not shown), such as a contactless payment attachment that plugs into an audio jack or plug of a mobile device.

The App Processor may enable execution of a mobile wallet application, which may include various user interfaces, which may leverage transaction data, wireless data connection, over-the-air data connection, or other means of data transmission. The data used in the application may be transmitted, for example, from external data sources. For example, the application and user interface may leverage information about products and/or services being purchased, information about the account or account holder, information about the merchant and/or other parties involved in a transaction, rewards information, promotional information, advertising information, and other useful information.

Software applications on client device 120 may include, for example, client application 124, which may be integrated with or separate from a mobile wallet application, which may be utilized to generate a notification of a price change for a transaction and to facilitate an associated price adjustment based on electronic image capture of a paper receipt for the transaction.

Image capture system 126 may include a camera that may be utilized to capture a picture of a paper document, such as a paper receipt. Image capture system 126 may also include a scanner that may be utilized to capture a picture of a paper document.

Client device 120 may transmit the electronic image of the captured picture to data extraction processor 140 via network 110. Content from the paper document may be extracted by the data extraction processor 140, which may include an OCR device that may convert images of text into characters. Specifically, data extraction processor 140 may enhance extract transaction receipt data from a paper receipt, which may include identifying store keeping unit (SKU) level inventory information. The specific extracted transaction information may also include specific details of the individual transaction items. The extracted data may be stored on data storage on data extraction processor 140. Data extraction processor 140 may transmit the enhanced customer transaction data to authentication server 153. Data extraction processor HO may be an external system to client device 120 or data extraction processor may be located on client device 120 or on account provider system 150.

The paper document may be OCRed through an automated, a manual, or a hybrid of the automated and manual process. An OCR device may include a comparison unit which compares the text from the OCR device with content relating to transactions that is stored in an account provider data storage 154. The comparison unit may identify matches between the text extracted from the image of a transaction receipt and the transaction data in the account provider data storage 154. Those matches may then be used to verify that the user utilizing client device 120 actually purchased the transaction items contained on the transaction receipt to in turn verify the authenticity of the transaction receipt itself. As such, the OCR image may be utilized to match a transaction receipt to a particular transaction record for a user stored on account provider system 150. This may include identifying additional information about the transaction, such as the geo-location tied to the transaction and/or a timestamp of the transaction.

For example, a method for extracting content from transaction receipt may include utilizing OCR software which may extract raw text from the transaction receipt. The raw text may then be searched using a regex to find identifying information that may match information associated with the transaction stored in account provider system data storage 154. For example, the identifying information may include SKU level inventory information, and specific details of the individual transaction items, such as the geo-location tied to the transaction, a timestamp of the transaction, and/or last four digits of the credit card used to complete the transaction.

If a match is found, the transaction receipt can then verify that the associated user actually made the purchase. Knowing the information about the transaction based on the enhanced transaction receipt data provides high confidence in verifying the transaction by the user when requesting a price match.

Comparisons can be made with the text extracted during the first pass in order to identify fields and the content of the fields, so as to confidently classify the extracted text as belonging to a certain field and having a certain format. Once the content of the transaction receipt is identified, the relevant content may be forwarded to account provider system 150 to find a price change.

The raw extracted text may also be parsed to classify the other text as belonging to a certain field. Predictive methods can be used to identify what text belongs in what field based on general properties of text in certain fields, such as dates, monetary mounts, addresses, names, etc. Numbers found on the statement can also be classified based on heir location with respect to certain keywords that may be found on the statement, such as “Credit Card No.,” “Merchant Name,” “Merchant Location,” “Total Balance,” “Date,” “Time,” and so on.

Upon extracting the enhanced transaction information from the transaction receipt, a unique key may be generated by authentication server 153. The key may include a token that may be utilized to determine whether the price matching should be authorized. For example, the enhanced transaction information may include the timestamp of the transaction. This unique key may be matched to a transaction record stored in data storage 154, and as such may be utilized to generate a reliability score for the OCRed image. In another embodiment, user credentials associated with a mobile application, such as client application 124, and user information stored on a user's mobile wallet may also be utilized to match the generated key. In another embodiment, for online purchases, a browser plugin may be utilized to access data from a checkout screen on a client device. This data may be similarly utilized to create a unique key, for example the key may be created from the confirmation number of the transaction order.

The generated unique key may be transmitted to price monitoring server 156 to determine whether to authorize price matching. If the unique key is matched to the transaction record, the system may authorize price matching. This generation of a unique key could eliminate the need for storing sensitive customer information, such as a credit card number and a cv code, for example, within a secure element on a client device. In effect, the keys could serve as single-use, or limited-use credit card numbers.

Price monitoring server 156 may be operated by a third party system or may be integrated with account provider system 150.

Account provider system 150 may include modules, systems, and interfaces to send and/or receive data for use in other modules, such as communication interface 159.

Front-end controlled domain 306 may be implemented to provide security for backend 318. Load balancer(s) 308 may distribute workloads across multiple computing resources, such as, for example computers, a computer cluster, network links, central processing units or disk drives. In various embodiments, load balancer(s) 310 may distribute workloads across, for example, web server(s) 316 and/or backend 318 systems. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overload of any one of the resources. Using multiple components with load balancing instead of a single component may increase reliability through redundancy. Load balancing is usually provided by dedicated software or hardware, such as a multilayer switch or a Domain Name System (DNS) server process.

Load balancer(s) 308 may include software that monitoring the port where external clients, such as, for example, user device 302, connect to access various services of a financial institution, for example. Load balancer(s) 308 may forward requests to one of the application servers 316 and/or backend 318 servers, which may then reply to load balancer 308. This may allow load balancer(s) 308 to reply to user device 302 without user device 302 ever knowing about the internal separation of functions. It also may prevent mobile devices from contacting backend servers directly, which may have security benefits by hiding the structure of the internal network and preventing attacks on backend 318 or unrelated services running on other ports, for example.

A variety of scheduling algorithms may be used by load balancer(s) 308 to determine which backend server to send a request to. Simple algorithms may include, for example, random choice or round robin. Load balancers 308 also may account for additional factors, such as a server's reported load, recent response times, up/down status (determined by a monitoring poll of some kind), number of active connections, geographic location, capabilities, or how much traffic it has recently been assigned.

A customer client device 120 may communicate with a merchant system via mobile client application 124. Client device 120 may utilize location-tracking systems and methods, such as GPS, to determine the current location of the customer client device. Upon determining the current location of the customer client device, client application 124 may send the current location to transaction system 152 via network 110.

Upon authorization for price matching, price monitoring server 156 may utilize a web crawler as an item level price tracker to facilitate price matching by searching for a price change of an item identified on a user's transaction receipt through the electronic data extraction. For example, prices for the transaction item may be obtained from web pages accessed by web crawlers and APIs. The web crawler process may automatically browse the web on a defined schedule, and may identify and index merchant sites selling the transaction item, which may include the merchant site where the transaction item was purchase, and may also include other external merchant sites. In an embodiment, a web may be embodied in a script that may parse HTML code of the sites to look for certain attributes associated with merchant sites. Price monitoring server 156 may determine whether a price change has occurred for the purchased item by comparing an original purchase price with a current price of the purchased item based on the determination that the purchased item has not been returned.

If price monitoring server 156 identifies that the price of a previously purchased transaction item has changed, price adjustment server 158 may automatically generate and transmit a notification to the user via an email, SMS message, etc., indicating the price change for the purchased item, based on the determination that the original price and the purchase price are different. The notification may be transmitted to client device 120. This generated notification may also indicate whether the price adjustment must be completed at a merchant location, or whether it can be completed electronically from the user's client device. Price adjustment server 158 may also automatically generate and transmit an email to the customer service department of the merchant from which the transaction item was purchased, requesting a price adjustment that is credited back to the payment instrument used in making the transaction. The price adjustment amount may be the difference between the original purchase price and the current transaction price. The email may include the picture of the paper receipt captured by client device 120 and processed by image capture system 126.

Transaction server 152 may receive acceptance of the price adjustment from merchant system 130, and in response, transaction server 152 may credit the customer account the price adjustment amount. In response, price adjustment server 158 may generate and transmit via communication interface 159 an electronic notification to merchant system 130 identifying the price adjustment.

In another embodiment, client device 120 may include a mobile device that may utilize location-tracking systems and methods, such as geo-fencing technologies, to determine the current location of a customer mobile device. Client application 124 may utilize this determined location to automatically, in real time, compare the current location of the customer mobile device to merchant locations identified by client application 124 for which price matching has been identified. If price monitoring server 156 determines that the location of the customer mobile device matches a merchant location for which price matching has been identified, client application 124 may transmit the current location of the customer mobile device to price adjustment server 158, which may, in real time, transmit a notification to client device 120 indicating that the customer has a price matched credit at the current merchant location.

Additionally, price monitoring server 156 may transmit a SKU number and an original purchase price of the purchased item to merchant system 130 to initiate the price matching processing, via communication interface 159. Merchant system 130 may use the SKU number to identify the purchased item and to search for the current price of the purchased item and may compare the original purchase price with the current price of the purchased item to determine whether there has been a price change. If merchant system 130 determines that the original purchase price and the current purchase price are different, it may generate and transmit via communication interface 138, an electronic notification to customer client device 120 identifying the price change, where the price adjustment amount is the difference between the original transaction price and the current transaction price.

The price matching processing may also be automatically initiated by price monitoring server 156 at a set time interval. For example, once a week, price monitoring server 156 may transmit a SKU number and an original purchase price of the purchased item to merchant system 130 to initiate the price matching processing, via communication interface 159. Merchant system 130 may use the SKU number to identify the purchased product and to search for the current price of the purchased item, and may transmit the current price to price monitoring server 153 for price matching processing. Additionally, the price matching processing may also be initiated manually by a customer when a customer transmits a request utilizing client application 124 on client device 120.

FIG. 4 illustrates an example method of generating a notification of a price change for a transaction and facilitating an associated price adjustment based on electronic image capture of a paper receipt for the transaction. The process 400 may begin at block 401. A client device 120 may utilize image capture system 126 to capture an image of a paper transaction receipt at block 402. Client device 120 may send the captured electronic image to data extraction processor 140, which may extract transaction data from the captured transaction receipt image at block 404. Data extraction processor 140 may include a comparison unit which compares the text from the electronically captured image of the transaction receipt with content relating to transactions that is stored in an account provider data storage 154. The comparison unit may identify matches between the text extracted from the image of a transaction receipt and the transaction data in the account provider data storage 154. The extracted transaction data may be transmitted to authentication server 153.

At block 406, the captured transaction data may be authenticated using authentication server 153. The electronically captured image may be utilized to match a transaction receipt to a particular transaction record for a user stored on account provider system 150. This may include identifying additional information about the transaction, such as the geo-location tied to the transaction and/or a timestamp of the transaction. The matches may then be used to verify that the user utilizing client device 120 actually purchased the transaction items contained on the transaction receipt to in turn verify the authenticity of the transaction receipt itself. As such, the electronically captured image may be utilized to match a transaction receipt to a particular transaction record for a user stored on account provider system 150. This may include identifying additional information about the transaction, such as the geo-location tied to the transaction and/or a timestamp of the transaction. Authentication server may also receive SKU item level detailed information associated with the transaction from a merchant system, which may be utilized by the authentication server to authentication not only the purchase, but also the price of the transaction.

If the captured transaction data is not authenticated, the process may end at block 422. If the captured transaction data is authenticated, the system may determine whether the item purchased for the identified transaction has been returned at block 408. Price monitoring server 156 may request associated transaction information for the identified transaction from transaction server 152. The requested transaction information may be utilized price monitoring server 156 to assess whether the purchased item has been returned. If the purchase item has been returned, the process may end at block 424 such that the price matching processing is not performed for items that have been returned.

If price monitoring server 156 determines that the purchased item has not been returned, the process may continue at block 408. Price monitoring server 156 may provide a price tracker, which may include a web crawler, to facilitate price matching by searching for a price change of an item identified on a user's transaction receipt through the electronic data extraction. For example, prices for the transaction item may be obtained from web pages accessed by web crawlers and APIs. If price monitoring server 156 does not identify a price change, the process may end at block 426.

At block 412, if a price change is identified, price adjustment server 158 may automatically generate and display on client device 120 a notification of the price change. This notification may include the amount of the change in price and the location of the merchant with the lower price. At block 414, price adjustment server 158 may automatically transmit notification of the price change to a merchant system. This notification may include a request for an electronic credit of the price adjusted amount to the payment instrument used in making the transaction.

At block 416, merchant system 130 may communicate with account provider system 150 to facilitate a price adjustment by crediting the customer account the difference between the price originally payed by the customer and the identified lower price, the price change. The merchant system may automatically receive a notification from account provider system 150 of the price adjustment and may store the adjusted transaction price in data storage 136 at block 418. As such, if the customer were to later return the price adjusted item, the merchant system would be able to pull the adjusted transaction price to credit the customer, rather than crediting the customer for the full original price, for which the customer has already been credited a portion.

The process may end at block 420.

The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are intended as illustrations of various aspects. Many modifications and variations can be made without departing from its spirit and scope, as may be apparent. Functionally equivalent methods and apparatuses within the scope of the disclosure, in addition to those enumerated herein, may be apparent from the foregoing representative descriptions. Such modifications and variations are intended to fall within the scope of the appended representative claims. The present disclosure is to be limited only by the terms of the appended representative claims, along with the full scope of equivalents to which such representative claims are entitled. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It may be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It may be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent may be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It may be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” may be understood to include the possibilities of “A” or “B” or “A and B.”

The foregoing description, along with its associated embodiments, has been presented for purposes of illustration only. It is not exhaustive and does not limit the invention to the precise form disclosed. Those skilled in the art may appreciate from the foregoing description that modifications and variations are possible in light of the above teachings or may be acquired from practicing the disclosed embodiments. For example, the steps described need not be performed in the same sequence discussed or with the same degree of separation. Likewise various steps may be omitted, repeated, or combined, as necessary, to achieve the same or similar objectives. Accordingly, the invention is not limited to the above-described embodiments, but instead is defined by the appended claims in light of their full scope of equivalents.

In the preceding specification, various preferred embodiments have been described with references to the accompanying drawings. It may, however, be evident that various modifications and changes may be made thereto, and additional embodiments may be implemented, without departing from the broader scope of the invention as set forth in the claims that follow. The specification and drawings are accordingly to be regarded as an illustrative rather than restrictive sense.
